WHY USE POWER CONTROL?

Static relays, static contactors and power controllers are required by industrial processes. Discover all good reasons to equip yourself with power controllers.

Static relays, statics contactors and power controllers are good replacements for electromechanical power contactors

Usually controlled by control loops, static relays, static contactors and thyristor power controllers handle the switching of the high electrical power required by industrial processes.

Indeed, their solid-state operating principle overcomes the contact wear problems encountered with electromechanical systems, which cause very costly production downtime. To increase the time between two contact changes, the contactor switching period is extended, leading to deterioration of the control loop.

Electromechanical contactors are designed to switch the power without worrying about the electrical disturbances generated on the network. The higher the power to be switched, the greater the disturbances on the network, which may cause malfunctions on the electronic equipment installed on the network.

Thyristor controllers offer a significantly longer life span with very high switching speeds. On high-value resistive or inductive loads in single-phase or three-phase systems, they offer high accuracy at the level of the control loop. The switching is performed when the network voltage reaches zero, thus minimizing electromagnetic disturbances.

Thyristor controllers offer a significantly longer life span 

On the top-of-the-range models, advanced limitation, control, load supervision and auto-surveillance functions boost the reliability of installations equipped with these devices.

Applications like annealing, drying, melting and heating of glass, plastics or metals often require optimized temperature control. Automation of temperature control ensures that precise temperatures are achieved and that the energy for heating is used efficiently. In this way, installation of a power controller enables more efficient use of raw materials and helps to reduce energy consumption by adapting it according to the requirements.

To sum up, find below the good reasons to buy a power controller

  • It's an economical solution
  • To overcomes the contact wear problems
  • To increase the time between two contact changes
  • Without worrying about the electrical disturbances generated on the network
  • Thyristor controllers offer a significantly longer life
  • For advanced limitation, control, load supervision and auto-surveillance functions
  • To reduce energy consumption
